In each episode the agent receives a percept and then performs a single action. crucially, the next episode does not depend on the actions taken in previous episodes.
02 Agents Pdf Rationality Control Theory For each possible percept sequence, a rational agent should select an action that is expected to maximize its performance measure, given the evidence provided by the percept sequence and whatever built in knowledge the agent has. Definition: a rational agent is an agent that always does the “right thing”. the right thing will (usually) ensure that the agent is successful (or survives). assume some performance measure (called its utility) which ranks how successful a particular action is for each agent given its environment. An agent program accepts percepts, combines them with any stored knowledge, and selects actions. a rational agent will choose actions so as to maximise some performance measure. (in practice try to achieve “good’ perfor mance.) ⇒ choose responses using condition action rules (or production rules ). Our plan in this book is to use this concept to develop a small set of design principles for building successful agents—systems that can reasonably be called intelligent. we will begin by examining agents, environments, and the coupling between them.

For each possible percept sequence, a rational agent should select an action that is expected to maximize its (expected) performance measures, given the evidence provided by the percept sequence and whatever built in knowledge the agent has. Examples of agents: human agent: uses eyes and ears as sensors; uses hands, legs, and mouth as actuators. robotic agent: uses cameras and infrared range finders as sensors; uses motors as actuators. 2. rationality definition: a rational agent is one that acts to achieve the best outcome (or best expected outcome under uncertainty). Fall 2024 lecture 2 designing rational agents an agent is an entity that perceives and acts. a rational agent selects actions that maximize its expected utility. Rationality is concerned with the agent’s capabilities for information gathering, exploration and learning from its environment and experience and is also concerned with the autonomy of the agent.
